Exclusive to Windows 10 for the foreseeable future. Who knows, hopefully GGG has the opportunity to expand to PS4. The more platforms the better. Exclusives are anathema to gaming.

my understanding is that PoE is coming to XBone, but not PS4 yet.

Seems silly as the PS4 playerbase is so much bigger than XO, I guess it is easier to port from windows to Xbone if you have started on the PC.

PoE is a good game but its way too grindy and min/max centered game gets almost impossible without an optimized build. Really not casual friendly and the game seems to get further and further away from casuals with every expansion, which is a shame IMO. In that respect I think D3 is better, and I hate saying that...
